About company

WaveStar

We had the chance to visit some company with our school. It is very interesting and rewarding to do that because we learn directly on the spot with professionals.

So we visited a big laundry for professional and Tulips company which produce food like sausage, salami etc. On there we saw the different methods of heating and speak about how to use less of energy. Also we went to see an experimental space with different Wind mill turbine. Unfortunately, the man who had to make the visit was sick so we didn’t go on the top of one which was very high.

We visited also a Wave power energy company. I will speak about it because it is directly the subject of our final project in our French school and because we are very interesting in Renewable Energy.

This company is on the west coast in Hanstholm. It is here that there are the best waves on the North because there are a lot of winds from everywhere (for sure a lot of winds). So it is the best place to install and test wave energy equipment.

Wave Star Energy machine

So we went there. At the beginning we had a coffee and a presentation about the company Wave Star. And after, we went on the platform in the middle of the sea to see how the machines work.

Wave Star company want to find new way to have clean energy from the wave with little effects on the environment. So after many research this company created the Wave star Energy. 

Floats moving with the waves 

Inside of the machine, the generators

This machine must be at the end a big machine able to produce a lot of electricity with a “simple” process. Several floats are attached by arms on a platform fixed on the sea floor. The floats move when the waves go up and down. These movements are transferred via hydraulics into the rotation of a generator which producing electricity.

This project was born with an idea of the Brother Hansen in 2000 and became real in 2003 when they purchased the right for it. At this moment, they knew that there was a huge commercial potential of wave energy. So they explored this project with the help of Aalborg University. And together they tried the concept created on a scale 1:40 model in 2004 in a wave test tank to see its performances. And in 2005 the machine on a scale 1:10 model was installing in the sea where the waves aren’t higher than in the North Sea, to see the first practical issues which can happening in the sea. Each time they tried to optimize the concept and at the end they make the equipment that we visited.

on Hanstholm

It’s on a scale ½ models which was built in 2009 and has been connected to the grid since February 2010. And since May 2010 a monthly production report has been made and delivered to the Danish company EnergiNet.dk which is responsible of the energy production in Denmark. This machine is still experimental; the electricity produced is not usable for the moment. But the resultants are good and encouraging for the future.

So they expect to increase and build machine with the best possible potency. And also, they hope to change the world’s mindset about how we can produce clean and unlimited energy.
